门脉流速与内径比值在门脉高压诊断中的意义

The Value of the Ratio between Portal Vein’s Velocity and Diameter in Diagnosing Portal Hypertension

目的探讨门静脉流速与内径比值在门静脉高压诊断中的价值。方法随机选取30例肝硬化门静脉高压患者,15例门体分流术后患者,30例慢性肝炎患者;50例正常人,测量门静脉流速v(cm/s)及内径d(mm),计算比值(v/d)对比分析。结果肝硬化门静脉高压组v/d为0.91±0.18;肝硬化门体分流术后组为1.07±0.21;慢肝组为1.25±0.27;正常组为1.65±0.21。肝硬化门静脉高压组v/d比值与其它三组有显著差异(P值<0.05,P值<0.001,P值<0.01),用d及v值比较门脉静脉高压组与其它组部分差异不大。结论v/d比值可作为肝硬化尤其是早期肝硬化门静脉高压的一项诊断标准。可观察门体分流术后疗效。

Objective To explore the value of the ratio between portal vein＇s velocity and diameter as a new method in diagnosing portal hypertension. Methods To select randomly 20 cases of liver cirrhosis with portal hypertension, 15 patients of posteriority to portosystemic shunt, 30 patients with chronic hepatitis and 50 normal cases, to measure portal vein＇s velocity and diameter of each group and compulate the ratio between portal veins velocity and diameter. The results obtained were contrasted and analysed. Results The ratio between portal vein＇s velocity and diameter had obvious difference between the group of liver cirrhosis with portal hypertension and other groups. Conclusions The ratio between portal vein＇ s velocity and diameter could be used as a useful index both in the diagnosis of liver cirrhosis, especially early liver cirrhosis with portal hypertension and in the observing the effectiveness of portosystemic shunts.
